WebApr 15, 2003 · Essentially, the procedure it uses is based on deterministic ARS approach and a set of standard ARS curves to be used to calculate the seismic laoding (for different soil profile types (soil profile type B to E)and Earthquake magnitudes) are given in "APPENDIX B" of the SDC. My question is: Webof 975 years, which corresponds to a 5% probability of exceedance in 50 years. The design Peak Ground Acceleration (PGA) has been evaluated as 0.62g from the design ARS curve and is controlled by the deterministic spectrum. The site to fault distance is also controlled by the deterministic spectrum at 1.0 seconds and is 1.25 miles. .
